[0022] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] In the embodiments of the present application, "at least one" means one or more, and "more" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. In the text description of the present application, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0024] The technical solution provided in the embodiment of the present application can be adapted to the mine ventilation control scenario. Mine ventilation control plays an irreplaceable role in coal mine safety production. For example, it can effectively protect the lives of miners, reduce accident risks, and improve the working environment.

[0025] In the mine ventilation system, the mine ventilation control is usually carried out based on the fixed tunnel structure and underground structure information in the mine. However, the above method cannot dynamically and specifically carry out ventilation control, resulting in low accuracy of ventilation control.

[0026] In order to solve the problem that ventilation control cannot be carried out dynamically and in real time in the prior art, thereby improving the accuracy and real-time performance of ventilation control, the present application proposes a mine ventilation control method, by obtaining the position of the tunnel in the mine to be controlled, the position of the structure in the mine to be controlled, and the position of the target object currently in the mine to be controlled; for each of the multiple merged tunnel sections corresponding to the tunnel, the wind resistance of the wind path corresponding to the merged tunnel section can be determined based on the physical properties of the merged tunnel section, the position of the structure and the position of the target object, so as to determine the ventilation volume corresponding to each branch in the ventilation network diagram, and based on the ventilation volume corresponding to each branch, control the ventilation device to ventilate the mine to be controlled. In this way, the wind resistance of the wind path is determined in combination with the position of the structure in the mine to be controlled and the position of the target object currently in the mine to be controlled, fully considering the influence of the structure and the target object on the wind resistance, so that ventilation control can be carried out dynamically and in a targeted manner based on the current wind resistance, effectively solving the problem that ventilation control cannot be carried out dynamically and in a targeted manner in real time in the prior art, thereby improving the accuracy and real-time performance of ventilation control.

[0027] It can be understood that the executor of the present method can be the monitoring equipment in the mine safety monitoring system, specially set up mine ventilation control equipment, computers or servers and other electronic equipment, or it can be a mine ventilation control device set in the electronic equipment. The mine ventilation control device can be implemented by software, hardware or a combination of both, and can be specifically set according to actual needs.

[0028] The mine ventilation control method provided by the present application will be described in detail below through the following specific embodiments. It is understandable that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0029] Figure 1 A flow chart of a mine ventilation control method provided in an embodiment of the present application, for example, see Figure 1 As shown, the mine ventilation control method may include: S101. Acquire the locations of tunnels and structures in the mine to be controlled, and the locations of target objects currently in the mine to be controlled; wherein the target objects include personnel and / or vehicles.

[0030] The location of the structure may include the lane and coordinates to which it belongs.

[0031] For example, when obtaining the tunnels in the mine to be controlled, the tunnel positioning method, such as the wire measurement method or the step method, can be used to obtain the tunnels in the mine to be controlled; the tunnels in the mine to be controlled can also be obtained through some positioning algorithms, etc., which can be set according to actual needs.

[0032] For example, when obtaining the position of a structure in a mine to be controlled, engineering measurement, positioning algorithm, on-site investigation, or drawing data consultation and other methods can be used to obtain the position of the structure in the mine to be controlled. The specific settings can be made according to actual needs.

[0033] For example, when obtaining the position of the target object currently in the mine to be controlled, a positioning card can be equipped on the target object. The positioning card can send a signal to the mine safety monitoring system in real time, which contains the precise position information of the target object, so that the mine safety monitoring system can accurately obtain the position of the target object; it is also possible to obtain the mine substation information in the mine to be controlled, and combine the mine substation information to obtain the position of the target object. Among them, the mine substation information can include its own level, mining area, tunnel, tunnel section and coordinates. This mechanism provides great convenience for managers, allowing managers to obtain and track the specific location of the target object in the mine in real time.

[0034] In an embodiment of the present application, by obtaining the position of the structure in the mine to be controlled and the position of the target object currently in the mine to be controlled, the wind resistance of the wind path can be determined in combination with the position of the structure in the mine to be controlled and the position of the target object currently in the mine to be controlled, that is, the following S102 is executed.

[0035] S102. For each of the multiple merged lane segments corresponding to the lane, based on the physical properties of the merged lane segment, the location of the structure, and the location of the target object, determine the wind resistance of the wind path corresponding to the merged lane segment.

[0036] The merged lane segment is obtained by merging multiple lane segments in the lane, and one merged lane segment corresponds to one air path.

[0037] For example, the physical properties of the merged tunnel segment may include the length, cross-sectional area, perimeter, friction resistance coefficient, etc. of the merged tunnel segment, which may be set according to actual needs.

[0038] For example, the structure may include a wind door, a wind window, a wind curtain, a wind barrier, etc., which may be specifically configured according to actual needs.

[0039] For example, in an embodiment of the present application, when obtaining multiple merged laneway segments corresponding to a laneway, the laneway can be first divided into multiple laneway segments based on the intersection points and guide wire points in the laneway; wherein each laneway segment is relatively independent and has a small segment of a specific length and direction. These laneway segments are important spatial division units in the mine, which help to accurately describe and analyze the spatial layout inside the mine; after obtaining the multiple divided laneway segments, the multiple laneway segments can be re-merged based on the positional relationship between all lanes in the mine to be controlled to obtain multiple merged laneway segments corresponding to the laneway.

[0040] Among them, each merged tunnel section is a continuous tunnel section with a greater length. Given that each tunnel section has its own parameters such as length, direction, and cross-sectional area, which will affect the distribution of wind flow underground, in the embodiment of the present application, by re-merging multiple tunnel sections, the number of nodes in the ventilation network can be effectively reduced, the network structure can be simplified, and the ventilation control efficiency and control accuracy can be effectively improved, thereby achieving the optimization and improvement of the mine ventilation system.

[0041] The above-mentioned determination of the wind resistance of the wind path in combination with the position of the structure in the mine to be controlled and the position of the target object currently in the mine to be controlled fully takes into account the influence of the structure and the target object on the wind resistance. In addition, the ventilation network diagram corresponding to the mine to be controlled can be constructed based on the positions of the wind paths and ventilation devices in the connected state in the wind paths corresponding to the multiple merged tunnel sections, that is, the following S103 is executed, so that the ventilation volume corresponding to each branch in the ventilation network diagram can be determined based on the current wind resistance, so as to dynamically and specifically perform ventilation control based on the determined ventilation volume corresponding to each branch, which can effectively solve the problem in the prior art that ventilation control cannot be performed dynamically and specifically, thereby improving the accuracy of ventilation control.

[0042] S103. Construct a ventilation network diagram corresponding to the mine to be controlled based on the positions of the connected air paths and ventilation devices in the air paths corresponding to the multiple merged tunnel sections; wherein the lines representing the connected air paths in the ventilation network diagram are branches.

[0043] For example, the ventilation device may include ventilation equipment and ventilation facilities, etc., which may be configured according to actual needs.

[0044] For example, when determining the connected air paths from the air paths corresponding to the multiple merged tunnel segments, a graph traversal algorithm, such as Depth-First Search (DFS) or Breadth-First Search (BFS), can be used. Starting from the starting point of the air inlet tunnel in the multiple merged tunnel segments, the entire graph is traversed to mark the visited nodes and edges; during the traversal process, if some nodes or edges are not visited, it means that the air paths corresponding to these nodes or edges are not connected and are not in a connected state; since the air paths that are not in a connected state will not affect the air flow distribution of the entire ventilation network, there is no need to participate in the construction of the ventilation network graph, and for the air paths that are not in a connected state, their related ventilation parameters, such as air volume, wind speed, resistance, etc., can be directly set to 0.

[0045] Considering that the mine ventilation network is a complex system composed of crisscrossing shafts and tunnels, the ventilation network diagram corresponding to the mine to be controlled can be constructed based on the positions of the connected air paths and ventilation devices, so as to abstract the complex mine ventilation system into a network diagram composed of nodes and branches, which is convenient for mathematical modeling and computational analysis, making the ventilation system more intuitive and easy to understand. The constructed ventilation network diagram includes node and branch information, which is an abstract description of the mine ventilation system, turning the ventilation system into a system composed of points, lines and their attributes, becoming a ventilation network. The lines representing the connected air paths in the ventilation network diagram are branches, and the points of the connecting lines are nodes. The ventilation network diagram is a data structure containing N branches and J nodes. Nodes can be divided into three categories: starting point, end point, and ordinary node.

[0046] S104. Determine the ventilation volume corresponding to each branch in the ventilation network diagram based on the wind resistance of each wind path corresponding to the multiple merged tunnel sections, and control the ventilation device to ventilate the mine to be controlled based on the ventilation volume corresponding to each branch.

[0047] For example, when determining the ventilation volume corresponding to each branch in the ventilation network diagram based on the wind resistance of each wind path corresponding to a plurality of merged tunnel sections, the ventilation network solution algorithm can be used to accurately calculate the ventilation volume corresponding to each branch in the ventilation network diagram according to the wind volume balance law, wind pressure balance law, resistance law, etc., so as to meet the ventilation needs of the mine, and control the ventilation device to ventilate the mine to be controlled based on the ventilation volume corresponding to each branch. In addition, the ventilation network solution is also helpful to analyze and optimize the performance of the mine ventilation system and improve ventilation efficiency.

[0048] It can be seen that in the embodiment of the present application, by obtaining the tunnels in the mine to be controlled, the positions of the structures in the mine to be controlled, and the positions of the target objects currently in the mine to be controlled; wherein the target objects include personnel and / or vehicles; for each of the multiple merged tunnel sections corresponding to the tunnel, based on the physical properties of the merged tunnel section, the positions of the structures and the positions of the target objects, the wind resistance of the wind path corresponding to the merged tunnel section is determined; based on the positions of the wind paths and ventilation devices in the wind paths corresponding to each of the multiple merged tunnel sections, a ventilation network diagram corresponding to the mine to be controlled is constructed; wherein the lines representing the connected wind paths in the ventilation network diagram are branches; based on the wind resistance of the wind paths corresponding to each of the multiple merged tunnel sections, the ventilation volume corresponding to each branch in the ventilation network diagram is determined, and based on the ventilation volume corresponding to each branch, the ventilation device is controlled to ventilate the mine to be controlled. In this way, the wind resistance of the wind path is determined by combining the position of the structure in the mine to be controlled and the position of the target object currently in the mine to be controlled, and fully considering the impact of the structure and the target object on the wind resistance, so that ventilation control can be carried out dynamically and targeted based on the current wind resistance, effectively solving the problem in the prior art that ventilation control cannot be carried out dynamically and in real time in a targeted manner, thereby improving the accuracy of ventilation control.

[0049] Based on the above Figure 1 In the embodiment shown, for example, in the above S102, for any merged tunnel segment, when determining the wind resistance of its corresponding wind path based on the physical properties of the merged tunnel segment, the location of the structure and the location of the target object, the structure and the target object can be regarded as an obstacle, because their existence will reduce the actual ventilation area of ​​the tunnel, thereby increasing the resistance of the wind flow passing through.

[0050] First, based on the position of the structure and the position of the target object, determine whether the structure and the target object are currently in the merged tunnel section. When the position of the structure and the position of the target object are both in the merged tunnel section, the wind resistance of the wind path corresponding to the merged tunnel section can be determined according to the following formula 1.

[0051] Formula 1 in, Indicates the wind resistance of the wind path, represents the friction resistance coefficient of the merged tunnel section, L represents the length of the wind path, U represents the circumference of the wind path, S represents the cross-sectional area of ​​the wind path, The wind resistance generated by the structure is Indicates the wind resistance created by the target object.

[0052] It can be understood that, in the above formula 1, if the target object includes a person and a vehicle, the above formula 1 can be transformed into the following formula 2.

[0053] Formula 2 in, represents the wind resistance caused by personnel, Indicates the wind resistance created by the vehicle.

[0054] It should be noted that, when the location of the structure and the location of the target object are not in the merged tunnel section, when determining the wind resistance of the wind path corresponding to the merged tunnel section, only the physical properties of the merged tunnel section can be considered, that is, in the above formula 2, , and The value of is 0; when the location of the structure is in the merged lane segment, but the location of the target object is not in the merged lane segment, when determining the wind resistance of the wind path corresponding to the merged lane segment, the physical properties of the merged lane segment and the wind resistance caused by the structure can be considered, that is, in the above formula 2, and The value of is 0 and can be set according to actual needs.

[0055] The above-mentioned combination of the position of the structure in the mine to be controlled and the position of the target object currently in the mine to be controlled jointly determines the wind resistance of the wind path, and fully takes into account the impact of the structure and the target object on the wind resistance, so that ventilation control can be carried out dynamically and targetedly based on the current wind resistance, which effectively solves the problem in the prior art that ventilation control cannot be carried out dynamically and targetedly, thereby improving the accuracy of ventilation control.

[0056] In the embodiment of the present application, the wind path corresponding to the merged tunnel segment is constructed in order to determine the path of the wind flow, which not only saves the key attributes such as the start and end point numbers of the merged tunnel segment, but also calculates the wind resistance of the entire path. In addition, when calculating the wind resistance of the wind path corresponding to the merged tunnel segment, in addition to considering the physical properties of the merged tunnel segment, such as the length, cross-sectional area, circumference and friction resistance coefficient of the merged tunnel segment, it further combines the position of the structure in the mine to be controlled and the position of the target object currently in the mine to be controlled to jointly determine the wind resistance of the wind path, fully considering the impact of the structure and the target object on the wind resistance, so that the flow of wind in the mine ventilation system can be more accurately calculated, so that the performance and safety of the mine ventilation system can be more accurately evaluated.

[0057] Based on any of the above embodiments, for example, in the above S104, when the ventilation volume corresponding to each branch in the ventilation network diagram is determined based on the wind resistance of the wind paths corresponding to each of the multiple merged lane segments, the specific implementation thereof can be referred to as follows: Figure 2 The embodiment shown.

[0058] Figure 2A schematic flow chart of a method for determining the ventilation volume corresponding to each branch in a ventilation network diagram based on the wind resistance of each wind path corresponding to a plurality of merged tunnel sections provided in an embodiment of the present application, for example, see Figure 2 As shown, the method may include: S201. For a first air inlet branch, a first return air branch, and a first internal branch that are not in a connected state in a ventilation network diagram, determine that the ventilation volumes of the first air inlet branch, the first return air branch, and the first internal branch are all preset ventilation volumes.

[0059] For example, the preset ventilation volume can be 0 or other values, and can be set according to actual needs. In the embodiment of the present application, the preset ventilation volume can be 0.

[0060] When calculating the ventilation volume corresponding to each branch in the ventilation network diagram, it is possible to first determine whether each branch is connected. For the first air inlet branch, the first return air branch and the first internal branch that are not in a connected state, there is no need to further perform wind network solution. The first air inlet branch, the first return air branch and the first internal branch that are not in a connected state can be automatically set to 0. In this way, by pre-judging the connectivity of each branch, unnecessary calculations for disconnected wind networks can be avoided, thereby saving a lot of computing resources and time.

[0061] S202. For the second air inlet branch and the second return air branch that are in a connected state in the ventilation network diagram, the internal branches in the second internal branch between the second air inlet branch and the second return air branch that are in a series state or a parallel state are merged to obtain multiple target branches; the multiple target branches do not include branches in series or internal branches in parallel.

[0062] It is understandable that if multiple branches are connected in sequence, end to end, to form a continuous channel, these branches can be called branches in series. The characteristic of branches in series is that the wind flows through each branch in sequence, and the wind volume does not change between different branches. If multiple branches start from the same node and are connected to different nodes, these branches are called branches in parallel. The characteristic of branches in parallel is that the wind can pass through multiple branches at the same time, and the wind volume of each branch may be different.

[0063] By way of example, in an embodiment of the present application, when merging the internal branches in series or parallel in the second air intake branch and the second internal branch and the second return air branch between the second air intake branch and the second return air branch, all the internal branches in series in the second internal branch between the second air intake branch and the second return air branch may be merged first to obtain a merged first branch; all the internal branches in parallel in the merged first branch may be merged to obtain a merged second branch; when the merged second branch does not include the internal branches in series or parallel, the merged second branch is determined as a plurality of target branches; on the contrary, when the merged second branch also includes the internal branches in series or parallel, the above-mentioned merging operation is re-executed until there are no branches in series or internal branches in parallel in the new merged second branch, and the new second branch is determined as a plurality of target branches.

[0064] By merging the internal branches in series or parallel as described above, the network structure of the ventilation network diagram can be effectively simplified, the topological structure of the ventilation network diagram can be made clearer, and independent loops can be found and air volume distribution can be calculated more quickly, thereby reducing the complexity and amount of calculation. The wind resistance of the branch obtained after the internal branches in series are merged can be shown in the following formula 3, and the wind resistance of the branch obtained after the internal branches in parallel are merged can be shown in the following formula 4.

[0065] Formula 3 Formula 4 in, It represents the wind resistance of the branch obtained by merging the internal branches in series. It represents the wind resistance of the branch obtained by merging the internal branches in parallel state, and n represents the number of internal branches to be merged.

[0066] It should be noted that, when the internal branches in series or parallel state in the second internal branch between the second air inlet branch and the second return air branch are merged, the internal branches in series state are merged first and then the internal branches in parallel state are merged as an example. Of course, the internal branches in parallel state can also be merged first and then the internal branches in series state, until there are no series branches or parallel internal branches in the multiple target branches after the merger. The specific setting can be made according to actual needs.

[0067] S203, adding a virtual branch connected to the ground surface between the air intake node and the air return node in the multiple target branches to obtain a target ventilation network diagram; wherein the virtual branch connected to the ground surface is used to characterize the surface ventilation condition in the mine to be controlled.

[0068] Add a virtual branch connecting the ground surface between the air inlet node and the air return node to ensure that the wind network can be solved normally. Set a reasonable wind resistance for the virtual branch connecting the ground surface. It can be set according to the actual situation and the needs of mine ventilation to ensure that the virtual branch connecting the ground surface can truly reflect the surface ventilation conditions.

[0069] S204. Based on the wind resistance of the wind paths corresponding to the multiple merged tunnel sections and the target ventilation network diagram, determine the ventilation volume corresponding to each branch in the ventilation network diagram.

[0070] For example, in an embodiment of the present application, when determining the ventilation volume corresponding to each branch in the ventilation network diagram based on the wind resistance of the wind paths corresponding to each of the multiple merged tunnel sections and the target ventilation network diagram, a tree can be first constructed based on the target ventilation network diagram, in which there is at least one passage between any two nodes and some branches that do not form a loop; and a residual tree can be constructed based on other branches except some branches in the target ventilation network diagram; wherein the weights of the branches in the tree and the residual tree are the wind resistance of the wind path corresponding to the branch, and in order to prevent iterative divergence and improve the iterative convergence speed, a minimum spanning tree is usually selected, that is, a tree with the smallest sum of weights on all branches; for an independent loop formed based on a residual branch in the tree and the residual tree, a residual tree is determined based on the ratio of the total air volume of the target ventilation network diagram to the number of independent loops. The initial air volume of the remaining branches is corrected based on the loop wind pressure balance law until the loop air volume of the remaining branches is within the preset accuracy range to obtain the corrected air volume; based on the corrected air volume and the direction of each target branch in the independent loop, the ventilation volume corresponding to each target branch is determined; for each target branch, when the target branch is a branch obtained by merging multiple first branches in series, the ventilation volume corresponding to each first branch is determined to be the ventilation volume corresponding to the target branch; when the target branch is a branch obtained by merging multiple second branches in parallel, the ventilation volume corresponding to each second branch is determined based on the merging method of the target branches; wherein the sum of the ventilation volumes corresponding to each second branch is the ventilation volume corresponding to the target branch.

[0071] In the mine ventilation network solution, independent loops refer to loops in the target ventilation network diagram that do not intersect with other loops. They represent independent ventilation paths in the target ventilation network diagram. By circling independent loops, the structure and characteristics of the target ventilation network diagram can be more clearly understood, providing a basis for subsequent solution and optimization work.

[0072] The initial air volume of the remaining branches is taken as the unknown quantity, and the amount of branches is expressed by the initial air volume of the remaining branches. Consider whether the total air volume of the target ventilation network diagram is a fixed air volume, for example, use the real-time cross-sectional wind speed of the total return air shaft for solution. If a fixed air volume is used, this fixed air volume is used as the total air volume, and the air volume at the operating point of the wind resistance and the total pressure characteristic curve of the fan is calculated as the total air volume. The ratio of the total air volume to the number of independent circuits is used as the initial air volume of the remaining branches.

[0073] When correcting the initial air volume of the remaining branches based on the loop wind pressure balance law, the Scott-Hinsley method and Newton method can be used for iterative calculation. The air volume correction calculation formula can be derived based on the loop wind pressure balance law, and the initial air volume of the remaining branches can be corrected step by step. The loop air volume of each remaining branch is corrected until the wind pressure is gradually balanced, and the loop air volume of the remaining branches is within the preset accuracy range, and the air volume is close to the true value. In order to deal with the situation where the solution does not converge, the number of solution iterations is limited. If it exceeds the maximum number of iterations and has not converged, the ventilation volume corresponding to each target branch is set to 0.

[0074] When the target branch is a branch obtained by merging multiple first branches in series, the merged branch can be disassembled to determine that the ventilation volume corresponding to each first branch is the ventilation volume corresponding to the target branch, as shown in the following formula 5.

[0075] Formula 5 in, represents the ventilation volume corresponding to the target branch, Indicates the ventilation volume corresponding to the nth first branch among the n first branches.

[0076] In the case where the target branch is a branch obtained by merging multiple second branches in parallel, based on the merging method of the target branch, the merged branch can be disassembled to determine the ventilation volume corresponding to each second branch, as shown in the following formula 6.

[0077] Formula 6 in, represents the ventilation volume corresponding to the target branch, Indicates the first branch of n The ventilation volume corresponding to the second branch.

[0078] In this way, the wind resistance of the wind path is determined by combining the position of the structure in the mine to be controlled and the position of the target object currently in the mine to be controlled, fully taking into account the impact of the structure and the target object on the wind resistance, so that ventilation control can be carried out dynamically and targeted based on the current wind resistance, effectively solving the problem in the prior art that ventilation control cannot be carried out dynamically and targeted, thereby improving the accuracy of ventilation control.
